Sinclair ZX-80In 1980 Sinclair released the ZX81. I wouldn’t play it if you gave me another one. : ) In 1980 when you said computer you meant room – they were that big. Bringing it to the hobbyist for under one hundred pounds and so tiny was a smart move. I have one here and a friend of mine recently asked me “Is it real?” People bought them just to look at. I was fortunate enough to go round to my granddad’s, a bit of a tinkerer, and have a go.

This was Clive Sinclair’s third machine. The Sinclair MK 14 came in kit form, followed soon after by the Sinclair ZX80. Which was almost immediately replaced by the ZX81.
